2. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






3. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






4. The solid structure formed by the fusion of the sacral vertebrae.






5. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






6. The collective name for 37-38 bones of the head; it houses the brain and all the special sense organs.






7. The cartilaginous disk located between the bodies of adjacent vertebrae; acts as a shock absorber for the vertebrae.






8. The cells that produce bone.






9. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






10. Skull bones; external bones of the face. These two bones make up most of the upper jaw and house the upper canine teeth - if present - and all of the cheek teeth.






11. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult






12. The first cervical vertebra; it forms the atlantooccipital joint with the occipital bone of the skull and the atlantoaxial joint with the axis.






13. The sievelike area of the ethmoid bone through which the many branches of the olfactory nerve pass from the upper portion of the nasal cavity to the olfactory bulbs of the brain.






14. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






15. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






16. Skull bones that are part of the internal bones of the face; also known as the nasal conchae. Four thin - scroll - like bones that fill most of the space in the nasal cavity.






17. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






18. A skull bone that is one of the internal bones of the cranium; forms the floor of the cranium and contains the pituitary fossa - a depressin that houses the pituitary gland.






19. The paranasal sinus in the ethmoid bone of horses and humans.






20. The last - most caudal sternebra; the _____ process.






21. A longitudinal ridge on the front of the proximal end of the tibia.






22. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






23. The bones of the pelvic limbs located between the tarsus and the phalanges.






24. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






25. The most caudal of the three pairs of bones that make up the pelvis.






26. Skull bones that are external bones of the cranium; form the dorsolateral walls of the cranium. They are large and well developed in dogs and cats - but small in horses and cattle.






27. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






28. The eardrum; a paper - thin connective tissue membrane that stretches across the opening of the external ear canal into the middle ear.






29. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






30. The shaft portion of a long bone.






31. Bones that are longer than they are wide; most of the limb bones are in this category.






32. The bones along the central axis of the body; made up of the skull - hyoid bone - the spinal column - the ribs - and the sternum.






33. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






34. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






35. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


36. The area of a bone that joins the head with the main portion of the bone.






37. The joint between the femur and the tibia; called the knee joint in humans.






38. A gliding joint in which two flat - articular surfaces rock on each other; this type of joint usually allows only the movements of flexion and extension.






39. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






40. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






41. The long bone of the brachium or upper arm.






42. The front limb.






43. A flat articular surface - such as between carpal bones and between the radius and ulna.






44. Bones that are relatively thin and flat; they consist of two thin plates of compact bone separated by a thin layer of cancellous bone. Includes skull bones and the scapula.






45. The bones of the tail portion of the spinal column.






46. A freely moveable joint; also known as a diarthrosis.






47. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






48. An alternate name for joint cavity.






49. Rib whose costal cartilage directly joins the sternum.
